3x Adapters (Danfoss RA, Danfoss RAV, Danfoss RAVL)

Intended use

With Comet Z-wave, you have acquired a programmable radiator thermo-

stat, which can be used to regulate temperature in closed rooms and thus

can contribute to a reduction in heat energy. Please use the regulator for

this purpose only.

Safety instructions

Never recharge, short-circuit or disassemble the batteries - danger

of explosion! Remove expired batteries from the device immediately.

Shield batteries from strong heat - increased risk of leakage!

Do not use new and old batteries together. Clean batteries and device

contact before installation if necessary. Keep batteries away from

children. Avoid contact with skin, eyes and mucous membranes.

Rinse areas affected by battery acid with clean water immediately

and seek medical advice.

Description

Comet Z-wave is a Z-Wave radio standard compatible

energy-saving radiator thermostat.

Use

The installation of the Comet Z-waves can easily be installed on all known

valve bottom sections; without dirt or water spots because the heating

circuit is not interrupted.

1. Fully unscrew the old thermostat, loosen the ﬁ tting

and remove from the valve.

2. 2. Remove the battery cover, by pressing it upwards on the marked spot

(1) and take it off its hinges (2).

(1)

(2)

Install the batteries as shown. Do not use rechargeable batteries!

Ensure correct polarity! PREP appears on the display. The motor will

start completely in order to facilitate installation. As soon as the regulator

is installation-ready, INST appears on the display. The ﬂ ashing radio

symbol signals that the device is ready to be enrolled. Start the enrolment

procedure (Inclusion) on your Gateway/Controller in order to include the

device in the network.

3. Screw the union nut (ring on product) on the valve. If the union nut does

not ﬁ t on you valve, you probably need an adapter.

4. Press the button in the battery compartment. The energy-saving thermo

stat shows ADAP in the display and carries out an initialisation run.

After initialisation, the energy-saving thermostat shows the main screen.

INFO When an error occurs, an error code is shown.

Look in the „Help“ table.

No adapter is required for the following valves:

Heimeier, Junkers Landys+Gyr, MNG, Honeywell Braukmann, since

these have thread dimensions of M30 x 1.5 mm. Adapters for Danfoss

RAV (pin must be put on the valve tappet) Danfoss RA and Danfoss

RAVL are enclosed.

An adapter is required for the following valves:

Herz M28 x 1.5 mm, Comap M28 x 1.5 mm, Vaillant 30.5 mm, Oventrop

M30 x 1.0 mm, Meges M38 x 1.5 mm, Ondal M38 x 1.5 mm, Giacomini

22.6 mm, Rossweiner M33 x 2.0 mm, Markaryd M28 x 1.0 mm, Ista M32

x 1.0 mm, Vama M28 x 1.0 mm, Pettinaroli M28 x 1.5 mm, T+A M28 x 1.5

mm or Gampper 1,2,6. These can be found at www.eurotronic.org

Please fully remove the plastic connectors before you use one of the

enclosed adapters! Please fully remove the connecting rods marked

in grey before installing the adapter!

Addition/removal to/from the network

In order to enrol and delete the device manually, start the enrolment /

deletion process of your central unit/gateway. Press and hold the

button in the battery compartment of the Comet Z-wave for 5

seconds. The device moves into installation position in order

to enable (de)installation.

Operation and display elements on the display

1. Bat tery empty

2. Comfort temperature active

3. Economy temperature active

4. Window-/frost protection function active

5. Wireless active

6. AUTO or MANU mode active

7. Adjusting wheel + and -

8. Button in bat tery compartment

Basic modes of operation

AUTO mode

The Comet Z-wave regulates temperature as per factory settings or

wireless set-up

Factory settings

Comfort temperature (Factory settings 22°C)

Economy temperature (Factory settings 18°C)

MANU mode

Comet Z-wave switches to MANU mode when you change the

temperature by hand on the adjusting wheel. The setting overwrites

the wireless set-up for two hours. After this, the setting changes

automatically to the previously-programmed setting. If you wish to

change the settings prior to this, you may do this via wireless.

Standby

The screen switches off 30 seconds after the last entry on the device

to save electricity. The display can be switched on again by turning the

adjusting wheel in any direction.

Frost protection, open window recognition and hard water protection

functions are automatically active.

Frost protection function

If the temperature falls below 6°C, the energy-saving thermostat

opens the valve until the temperature rises above 8°C again.

This stops the radiator from freezing.

Hard water function

To avoid calciﬁ cation of the radiator valves, the energy-saving

thermostat carries out a hard water protection cycle once a week.

Open window function

If the temperature falls sharply, open window recognition is activated

and the open window active symbol is shown. In this instance, the

valve is closed for 15 minutes.

Uninstallation

In order to uninstall the energy-saving thermostat, press and hold the

button down for 3 seconds. The device moves into the installation po-

sition. When the installation position has been reached (display shows

INST), youmay take out the bat teries and unscrew the energy-saving

thermostat from the valve.

Cleaning

Use only a dry to lightly-damp cloth to clean the Comet Z-wave.

Avoid using chemical solvents,. They may damage the device.

is it calciﬁ ed after

the summer pause/

heating pause?

Adjust the temperature of

the boiler water.

Remove the Comet

Z-wave, move the valve

back and forth per hand or

with a tool.

Valve does not close

completely. It may be

that the closing point

of your valve seat has

shifted.

Adapt again (see

“Adapting”) Move the

valve stem several times

by hand, it may be that

adaptation is impossible

because your valve is

calciﬁ ed or the seat

no longer performs its

function.

Pressure

piece falls

out (This

can also

cause an

E1-error)

Due to an endless

thread the pressure

piece, which is situ-

ated at the bottom,

can fall out if the

device has not been

af ﬁ xed on the

valve.

Put in the pressure

piece. Press the Button

for 3 sec.

The endless thread is

rotating now and ﬁ xes

the pressure piece

again. Just install it to

the radiator and adapt

it once again.

E1-E3 Press the button for 3 seconds. The fault indication

is deleted. The device moves to the mounting posi-

tion (display shows PREP or INST).

E1 No adaptation
